On the way: Thunderstorms, torrential rain, possible flooding

Officials said a storm system is expected to hit northeast Illinois this afternoon that could produce scattered thunderstorms, torrential rain, gusty winds and possible flooding.

According to the National Weather Service, the storms will move eastward across north central Illinois early this afternoon. Once those storms meet the humid air, it may cause scattered thunderstorms for parts of the northeastern region and northwest Indiana into the evening, said officials.

Once the system hits, there is the potential for torrential rainfall and flash flooding. Winds have the possibility of picking up to 40 mph in some areas, said officials.

A flash flood warning was issued Friday night for southern Cook and DuPage counties. The warning was expected to expire by 2:30 p.m. Saturday.
